The document discusses the evolution from traditional teacher-centered classrooms to modern student-centered learning environments. It notes that educational theorists like John Dewey advocated for active, individualized pedagogies focused on the student in the early 20th century. However, traditional classrooms with direct instruction and rows of desks remained common. But now, societies and economies value knowledge and information sharing over factory work. Modern classrooms integrate technology, allow independent and group work, and facilitate more self-directed learning with the teacher as guide.
